STUD-SETTING MACHINE.

Application filed July 6, 1912.

To all whom it may concern:

Be it known that I, ARTHUR BATES, a subject of the King of England,residing at Leicester, Leicestershire, England, have invented certainImprovements in Stud-Setting lfachines, of which thefollowingdescription, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indicating likeparts in the several figures.

This invention relates to machines for setting lacing studs or hooks insheet material such as the uppers of boots and shoes, and has for itsobject to improve machines of this class and render them capable ofoperation in a more convenient and satisfactory manner than formerly. I

In stud setting machines of this class the studs are placed in bulk in areservoir from which they are fed successively to a position in linebetween the setting dies so that when the setting dies are forced towardeach other the stud is clenched in the work. The work is then advancedfor a distance equal to the spacing between successive studs and anotherstud inserted. One object of the invention is to provide a machine inwhich the work may be fed in either direction relatively to the settingdies. This in practice has been found to be advantageous in that, if forexample studs are to be set in the left quarter of a shoe uppercommencing from the lowermost point and feeding the work from right toleft, then in setting studs in a right quarter it is possible to beginalso at the lowermost point and feed the work from left to right. Inusing a machine where the work must be fed always in the same directionit has been necessary to begin at the lowermost point in one quarter andthe uppermost point in the other quarter and this has caused undue delayand a considerable amount of variation in the position of the lowermoststud in the two quarters of the upper. The present invention, therefore,contemplates a machine for setting lacing studs or the like having, incombination, setting dies relatively movable toward one another toeffect the setting operation, and means for positioning the stud for thesetting operation so constructed and arranged as to permit the work tobe fed with the clenched stud either from left to right or from right toleft.

As herein shown, one means for positioning the stud comprises threeguiding or po- Specification of Letters Patent.

sitioning members so arranged that as a stud is moved between the diesit will come into contact with the three members. Subsequently one ofthese members is moved relatively to the others so that the work,together with the clenched stud, can be fed either in the directionalong which the stud was moved into position between the dies or in adirection opposite thereto.

Preferably the positioning member which is moved relatively to the othertwo comprises a stop which projects when one of the setting dies isretracted into the path of the stud located between the other twopositioning members. The stop is mounted upon a stationary part of themachine and is left behind when the die and the other two positioningmembers are moved to effect the setting operation, so that the clenchedstud is free to be moved in the direction in which it was formerlyprevented from being moved by the stop.

Preferably one of the setting dies is provided with a part which ismoved relatively thereto after a stud has been received so as to holdthe stud in correct position. As herein shown the movable part isprovided with a pair of cooperating guides or flanges which registerwith the raceway and receive a stud therefrom when the two are broughtinto register.

These and other features of the invention will be best understood andappreciated from the following description of a preferred embodimentthereof selected for purposes of illustration and shown in theaccompanying drawings, in which,

Figure 1 is a view in front elevation of the lower part of the machinewith certain parts in section;

Fig. 2 is a similar view to Fig. 1 with other parts in section andshowing a different stage in the operation of the machine;

Figs. 3 and 4 are respectively plan and sectional views of the gagemechanism, and

Fig. 5 is a view in side elevation of the lower part of the settingspindle.

The machine comprises a setting die 2 forming a part of thereciprocatory spindle 4, a raceway 6 down which the studs pass bygravity and an anvil or upsetting die 8 which cooperates with the die 2to clench the barrel of a stud upon the lower side of the work.

The spindle 4 of the setting die is mounted to slide in verticalbearings, one of which is shown at 10, in a part of the frame 12 of themachine, and is actuated through suit able connections from a treadle,not shown. A spring 14 is provided to return the spindle 4 to its raisedposition, resting at one end upon the stationary bearing 10 and at theother bearing against a collar secured upon :the spindle of the settingdie. The lower part of the spindle 4 which constitutes the setting dieis concaved or recessed, as at 3, to form a seat for the head of thestud during the setting operation.

At its lower end the spindle 4 is partially surrounded by a sleeve 18having a portion cut away at the side adjacent to the raceway 6. Thesleeve 18, for a purpose hereinafter explained, is capable of a slightamount of sliding movement lengthwise of the spindle 4 and is attachedto the end of the spindle by springs 20 which tend to draw its lower endinto contact with the lower end of the spindle. Each of the springs 20is attached at its lower end to a pin 22 projecting from the sleeve andat its upper end to a pin 24 fixed in the spindle. A slot 25 is providedin-each side of the sleeve to permit the latter to move downwardly inrelation to the spindle and in opposition to the springs. When thespindle is moved upwardly and before it reaches its initial position,the upperendof the sleeve 18 encounters the lower end of the bearing 10,the springs20 permitting lost motion to occur between the sleeve and thespindle.

Secured to or formed as part of-the end of the sleeve 18 are the guidemembers or flanges 26 as shown in Fig. 5. These flanges form acontinuation of the raceway 6 when the spindle 4 is in its raisedposition and so are adapted to engage the neck of a stud as it isdelivered from the raceway. To maintain the lowermost stud which haspassed from the raceway in a. central position beneath the setting die 2a stationary stop 28 is provided which projects slightly below the diewhen the spindle 4 is in its elevated position. This stop also acts toprevent the stud delivered to the die from being pushed out through thesleeve by the weight of the studs remaining in the raceway.

In a preferred construction the stop 28 is formed of yielding materialand is attached by a screw 29 to the upper part of the bearing 10. Thespindle 4 is provided with a longitudinal slot to receive the stop 28.A. set screw 34is threaded into the bearing 10 and engages the stop 28at its inner end so that the latter may be adjusted laterally relativelyto the spindle in order to insure the proper positioning of the stud inrelation to the setting die.

The raceway 6 is located on one side of the spindle 4 and is disposed ina substantially vertical position so that the studs supplied to it fromany suitable reservoir sion will gravitate down the raceway to thesetting die. The lower end of the raceway is curved in a vertical planeso as to deliver the studs beneath the end of the spindle 4 insubstantially upright position, the spindle being cut away at one sideto accommodate the end of the raceway.

The anvil or upsetting die 8 against which the end of the stud barrel isclenched by the action of the setting die 2 is located below the latterand .directly in alinement with it. The upsetting die may be shaped tocorrespond with the particular style of stud to be set and is providedwith a projecting portion or nipple at the center upon which the barrelof each stud is forced during the setting operation.

The machine is provided with a pairof pointed spacing gages 36 and 38arranged one on each side of the upsetting die and at equal distancesfrom it. These gages constitute means whereby both left and rightquarters of a shoe may be located so as to have the studs set in thematequaldistances apart beginning from either the uppermost or thelowermost stud according to .the requirements of the work in hand. Thedistance of the gages 36 and 38 from the .up-

setting die may be varied forithe purpose of altering the spacing of thestuds and :the

arrangement is such that the symmetrical disposition of .the gages ismaintained .inall their adjusted positions. For this purpose the'gagesare pivoted at 39 to a carrier which .in this instance comprises .aslide 40 of triangular cross section as shown in Fig. 1. The slide 40 isadjustably mounted in an undercut slideway formed in .an exten- 13 oftheframe. Adjustment .of the gages 36 and 3.8 is effected by .a screw 42having a milled head for the convenience of the operator and right andleft threaded portions, each threaded into a nut in one of the gages.The screw is provided with a collar 44- at its center whichengages in agroove in the slide 40 and so prevents longitudinal movement of thescrew.

The front end of the slide 40 forms an edge gage 46 for guiding the workin the stud setting operation and determining the distance in from theedge of the work at which the stud is to be set. By adjusting theposition of the slide 40 the position of the edge gage is varied and forthis purposea screw 48 is threaded into a bore in the rear end of theslide 40 and is connected to the Xtension 13 of the frame by collars insuch a manner as to be free for rotation but prevented from longitudinalmovement. As the spacing gages 86 and 38 are pivoted upon the edgegage-slide 40 it follows that when the edge gage isadjusted rearwardlyor forwardly'to vary the distance from the edge of the work at which thestuds are to be inserted the points of the spacing gages 36 and 38 arecorrespondingly moved so that they are always against the edge of thework notwithstanding its position with relation to the setting dies.

The operation of the machine will doubtless be apparent from theforegoing description of its parts but for the sake of clearness a briefdescription of what occurs in the actual use of the machine will begiven.

Assuming the spindle a to be held in its raised position through theaction of the spring 1% a stud will then be delivered from the raceway 6to the guide flanges 26. On account of the lost motion connectionbetween'the sleeve 18 and the Spindle 4 the setting die 2 will occupy aposition at a sufiicient distance above the flanges 26 to afford spacefor the head of a stud to pass freely beneath it, while the flangesthemselves are held in alinement with the raceway by the engagement ofthe upper edge of the sleeve 18 with the bearing 10 as shown in Fig. 1.The stud received upon the guide flanges 26 moves into contact with theadjustable stop 28 by which it is located centrally beneath the die 2.

The work is placed between the die 2 and the upsetting die 8 and thetreadle operated to cause the descent of the spindle 1. During theinitial part of the descent of the spindle i the setting die 2 engagesthe head of the stud, the stud being thereafter held in position by theaction of the springs 20 upon the sleeve 18. It will be apparent thatthe stud is gripped in this manner before the spindle descendssufficiently to carry the stud out of contact with the stop 28.

The continued downward movement of the spindle a forces the barrel ofthe stud through the material and over the nipple of the upsetting dieand effects the setting operation. The spindle i is then allowed torisesufficiently to lift the clenched stud clear of the nipple of theupsetting die so that the stud can be moved laterally from beneath thedie 2 along the guide flanges 26 in either direction lengthwise of theline in which the studs are being inserted. A uniform spacing betweenthe studs is secured by moving the material to bringeach successive studinto register with one or the other of the spacing gages 36 or 38according to the direction in which the work is fed, and then settingthe neXt stud with the material so positioned.

The machine herein shown has been described as being treadle operatedbut it will be apparent that it could be equally well operated by power.It should be noted also that the machine may be adapted for handlingstuds of different types from the studs herein shown and that the use ofthe machine is not limited to any particular type of stud and that manyfeatures of the invention may be embodied in machines for setting othertypes of studs, rivets, eyelets, or similar articles.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent of the United States is:
